What Is a Korean Sweet Potato?

The word ‘goguma’ (고구마) refers to a sweet potato in the Korean language. In South Korea, there are five popular types of sweet potato: 

  • Purple Sweet Potatoes (Jeok Goguma 적고구마)
  • Chestnut Sweet Potatoes (Bam Goguma 밤고구마) 
  • Pumpkin Sweet Potatoes (Hobak Goguma 호박고구마)
  • Honey Sweet Potatoes (Kkul Goguma 꿀고구마) 
  • ​​Water Sweet Potato (Mul Goguma 물고구마)

All of these sweet potatoes taste extremely delicious! The most famous type of Korean sweet potato outside of South Korea is probably the chestnut variety. You can learn more about Korean sweet potatoes in my ingredient article on the subject. I also recommend checking out my recipe for baked Korean sweet potatoes!

If you cannot find any type of Korean sweet potato, you can use any type of sweet potato available to you at your grocery store. No matter what, it is a healthy snack!

Korean Dried Sweet Potato Tips & Tricks: 

Here, I list some helpful tips & tricks to help you make this incredibly easy Korean dried sweet potato recipe. If you have any questions, leave a comment below or email me at [email protected]! I hope these tips help! 

  • First, I recommend washing your sweet potatoes with cold water.
  • You can either bake or steam your sweet potatoes for this next step. To bake them, place them in the oven at 425°F for 45-60 minutes. I recommend turning them about halfway through the baking process. Or, to steam the potatoes, cook them for an hour and a half in the steamer basket. I tend to bake mine as I feel as though I can walk away from the oven more easily than the stove to get things done around the house! 
  • Once you finish baking or steaming your sweet potatoes, let them cool for 5 to 10 minutes. Then, peel them. 
  • Cut your potatoes into slices (approximately ⅓ inch thick). Then, place the slices into your dehydrator. Then, set your dehydrator to 135°F. Let the slices cook for 12 hours.

Now that we learned about some tips & tricks, I want to answer some questions you may have about this recipe! If I do not answer your question, feel free to leave a comment in the section below or email me at [email protected].

Does This Recipe Contain Major Allergens? (Gluten, Soy, Etc.)

Before listing all of the major allergens, I want to state that all of my recipes are naturally gluten-free. On this blog, I only use and recommend gluten-free ingredients and brands. That being said, I list gluten as a potential allergen when necessary– this is because many Korean ingredients (such as soy sauce, gochujang, and doenjang) contain gluten unless you specifically buy gluten-free versions. Not only is this true for gluten, but it is true for other major allergens as well. As such, I always list allergy substitutions in the next section of my post. 

This recipe does not contain 9 of the 9 major allergens. It does not contain: 

  • Peanuts
  • Fish
  • Crustacean Shellfish
  • Eggs
  • Milk (Dairy)
  • Sesame
  • Tree Nuts
  • Wheat (Gluten)
  • Soybean

This recipe does contain 0 of the 9 major allergens.

Is This Recipe Vegetarian or Vegan?

Excitingly, this recipe is naturally vegetarian and vegan!

Where Can I Buy Korean Sweet Potatoes?

While you can buy ‘bam goguma’ (chestnut sweet potatoes) at Whole Foods throughout the United States, you cannot buy other varieties of Korean sweet potatoes in your local well-stocked grocery store. Instead, I recommend going to a Korean or Asian grocery store. 

Also, if you do not want to dehydrate your own sweet potatoes, you can buy dried Korean sweet potato snacks online and in Korean grocery stores. That being said, they have way less flavor than the homemade version.

How Should I Store These Korean Dried Sweet Potatoes?

You can store these Korean dried sweet potatoes in an airtight container in a cool, dark place (like a pantry). At room temperature, you can store this for up to a week. Or, you can freeze them for up to a month.
